LASTING MACHINE FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 270,282, dated January 9, 1883.

Application filed September 13, 1982. (No model.)

To all whom it may concern:

Be it known that I, LOUIS COTE, of St. Hyacinthe, in the county of St. Hyacinthe and Province of Quebec, Canada, have invented certain new and useful Improvements in Lastin g Boots and Shoes and Machinery therefor, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to an improved process of lasting boots and shoes and to mechanical devices for applying said process, and has for its object a more complete and perfect fitting of the upper to the lastdn all its parts, with avery material reduction in the cost of the mechanical devices for automatically stretching and securing the upper upon the last as compared with the lasting-machines now in use; and it consists, first,in the use, in alasting-machine, ofa revolving wheel having a peripheral surface adapted by roughening or otherwise to act by frictional contact upon and carry along with its surface a shoe-upper when pressed thereto, in combination with mechanism for imparting to said wheel a continuous rotary motion in one direction and an automatic nail-driving mechanism.

It further consists in the combination of a wheel having its periphery roughened 0r otherwise adapted to act by frictional contact upon and stretch the up-penuponntheuli fifi when presented thereto, mechanism for imparting to said wheel a continuous rotary motion in one direction, a nail-drivin g mechanism, and mechanism for intermittently throwing the naildriving mechanism into-and out of action at the will of the operator without alfecting the revolution of the wheel.

Figure 1 of the drawings is a side elevation of a machine embodying my invention. Fig. 2 is a frontend elevation of the same. Fig. 3 is a front elevation of the roughened frictional wheel for straining the upper over and pressing it upon the inner sole. Fig. 4 is a section through the axis of a frictional wheel of a modified construction, and Fig. 5 is a partial vertical section on line m w on Fig. 2.

A is the frame of the machine, constructed and adapted to be secured by its flange A to a bench or column, and having mounted in suitable bearings formed therein the shafts B and (J. The shaft B has firmly secured upon its. rear end the driving-pulley D'and the spurgear wheel E, which meshes into and imparts motion to the gear E, which in turn meshes into and impart-s motion to the spur-gear wheel F, mounted loosely upon the shaft O, and constructed and arranged to intermittently en gage with the conical wheel G, firmly secured upon said shaft 0, so as to be compelled to revolve with it. The gear-wheel F is arranged. to have a slight endwise movement upon the shaft 0, and is moved into and out of engagement with the wheel G by means of the forked elbowlever H, the rod 1, and atreadle and spring attached thereto. (Not shown in the drawings.)

J is a roughened metallic wheel, firmly secured upon the front end of the shaft B, with its front radial face in close proximity to the path of the nail-driver. This wheel may be made of metal, as above described, with its peripheral surface roughened, as shown in Fig. 3; or itmay have its periphery grooved to receive a hoop or band of rubber, J,'as shown in Fig. 4, without departing from the princi ples of my invention.

trated in the drawings are well-known devices,

Iwhich goto make up a machine adapted to feed a wire vertically a short distance at stated intervals, cut from said wire pieces of a given or determined length, and drive them into any object held firmly beneath the nose of the machine, and hence they will be only briefly referred to here.

Near the front end of the shaft 0 is secured thereto a feed roll (shown in dotted lines at a in Fig. 2) having teeth upon its periphery, which engage with corresponding teeth upon the roll I), mounted in movable bearings, and arranged to be intermittently moved toward and from the roll a, and made to grip the wire for a longer or shorter interval to determine the length of nail to be cut by mechanism not shown in the drawings, but in common use and well known.

- Kjs the driving-bar; c, the driver; L, the cam for lifting the driver-bar; d, the spring for throwing the driver-bar down after it has The remaining parts of the machine illns- 2 eaexeae been raised e, the cutting-off die; M, the lever, and N the cam for operating the cuttingot't' die; 0, a ratchet-disk, and a pawl cooperating therewith to serve as a stop for the nailing device.

Itis obvious that any other kind of nailinginachine than theoue shown and described may be combined with my improved frictional lasting-roll without affecting the principles of my invention.

The machine shown and described is designed to be used by the operator holding the shoe or boot to be lasted in the desired position beneath the wheel J and the nosefot' the machine; but ajack for holding the shoe may be used, if desired.

The operation of my inventionis as follows: The boot or shoe upper is placed upon the last in the desired position, and secured thereon in the usual way, by a tack at the heel and another at the toe, after the leather has been strained in the direction of the length of the last and the toe of the upper has been turned down upon theinner sole. The operator then takes the last with the upper thereon in both hands, with the tread-surface of the last up ward, and presents it to the under surface of the wheel J, which is moving toward the front of the machine, as indicated by the arrow, and pressing the tread-surface of the last upward till the section of the upper in contact with said wheel is pressed hard upon the inner sole,

, and is drawn tight to the last by the frictional upon the inner sole, the'operator removing his foot from the treadle as soon as the nail is driven, when the operation of the nailing devices ceases till the treadle is again depressed.

The operator then moves the shoe along a short distance and repeats the operation, and. so continues tillthe shoe is completely lasted,

the work being performed step by step or section by section, the operation in that respect being somewhat analogous to the operation of lasting boots and shoes by hand.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine for. lasting boots and shoes, a wheel having its periphery roughened or otherwise adapted, substantially asset forth, to act by friction upon and stretch the upper upon the last when presented thereto, in combination with mechanism for imparting to said wheel a continuous rotary motion in one direction and an automatic nail-driving mechanism, substantially as described.

2. In a machine for lasting boots and shoes, the combination of a wheel having its periphery roughened or otherwise adapted, substantially as set forth, to act by frictional contact upon and stretch the upper upon the last when. presented thereto, mechanism for imparting to said wheel a continuous rotary motion in onedirectiou, a nail-driving mechanism, and a mechanism t'orintermittently throwing the nail-driving mechanism into and out of. action at will without att'ecti-ng the revolution of the wheel, substantially as described.

3. The combination of thefrictional wheel J, the shaft B, the shaft 0, a nail-driving mechanism operated by said shaft 0, a train of gearing connecting the shafts B and O, a clutch, and shipping mechanism for intermittently throwing the nailing mechanism into and out of action, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 9th day of September, A. D. 1882.
